# Example: Multi-agent pipeline

A **three-stage blog writing pipeline**: **content creator** → **clarity editor** → **SEO optimizer**. Each stage is a separate agent; the workflow `entry` runs them sequentially with shared `ctx.state`.

## Pipeline

```
  input { topic, keywords, audience, tone, wordCount }
         │
         ▼
  content-creator ──► draft markdown
         │
         ▼
  clarity-editor ──► refined article
         │
         ▼
  seo-optimizer ──► article + metaTitle + metaDescription + slug
```

{% hint style="success" %}
Set **`observability: true`** to see each AI step (draft, edit, SEO) in the workflow dashboard with token usage and latency.
{% endhint %}

## Why sequential agents?

| Benefit                    | Explanation                                                  |
| -------------------------- | ------------------------------------------------------------ |
| **Separation of concerns** | Each agent has one prompt specialty                          |
| **Debuggable**             | Inspect `ctx.state.draft`, `ctx.state.refined` between steps |
| **Observable**             | Three labeled steps in the dashboard                         |
| **Reusable**               | Agents can be recomposed in other workflows                  |
